Footwear layout

ABSTRACT

A shoe construction is disclosed wherein a sole piece and an intermediate layer of cardboard are attached to a heel by a metal plate. On top of the metal plate is situated a reinforcing shank piece which extends to the instep of the shoe. The heel has an upwardly extending shoulder and all of the aforementioned layers have a height less than the height of a shoulder whereby a strong uniblock construction is obtained.

1 Claim, 4 Drawing Figures PATEMEU SEP 1 75 FIG.2

FOOTWEAR LAYOUT The use of a metal shank setting the shape and concavity or inward bend of the shank portion of footwear is not strictly a novelty nor does it endeavour to claim its use as a special privilege.

However, the recommended arrangement is indeed new inasmuch as conventionally the metal shank in question is used by fitting it by some suitable means to the insole, which lastly overlaps the sole and the whole then secured to the heel by nailing, clipping or other ways and means known in themselves, with which an additional piece is required at least covering the heel area to hide the heads of the securing details.

In the new arrangement claimed, the sole is attached to the heel and a flat piece of preferably cardboard material is set between sole and shank, stuck to the sole and joining shank to heel by means of suitable wood screws or nails.

With this arrangement, the joint between sole and heel is strengthened, the shank maintaining the curvature needed in the footwear according to whether it is high or low-heeled, but with the insole completely nail-free. so that it can be secured with adhesives commonly used in shoemaking, without need for additional parts to hide the nailing details. In addition, this allows the sole not to be seen in open-heel shoes as the butt stays hidden in the associated offset at the top end of the heel, its outer edges fitting onto the sole itself.

Summarizing: in the common arrangement the shank is fitted to the insole and both are simultaneously joined to the heel and require another cover-piece. In the recommended arrangement the shank is fitted to the heel and not previously to the insole, which is lastly joined to the sole-heel unit with appropriate adhesive.

FIG. 1 shows an elevational and longitudinal section of the layout of the various details constituting the soleheel combination strengthened with the shank.

FIG. 2 pertains to a groundor floor-plan view FIG. 3 depicts overlaying of the insole on the preshaped sole-heel unit.

FIG. 4 shows the final simplified improved finish.

The conventional heel l in shape and material has on its upper side or face an offset 2 where the heel of sole 3 fits, this having a preferably cardboard strip 4 stuck to its upper shank and heel, slightly oversize in relation to the shank outline 5.

The interjoined sole 3 and strip 4 are secured to heel l by suitable woodscrews, staples or nails 7 with a preferably metal plate 6 inserted to reinforce this joint and prevent loosening of the aforesaid securing detail heads.

The shank-piece is overlaid on the thus-shaped assembly, this in turn similarly joined to the heel by nailing or stapling means. This preferably metal and suitably rigid shank piece is to maintain shape of the footwear sole or instep, whether highor low-heeled, this consisting of a metal strip with a lengthwise slot strengthening the general curvature, leaving both ends flat for their better fitting with the footwear sole.

A strong monoblock assembly is thus achieved independent of the insole as distinct from the common method of securing insole to shank, and which subsequent nailing forms nicks or cracks having to be hidden by means of coveror false-pieces.

In fact, the insole (see FIG. 3) consisting of a lower support or bed 8 and an upper cover 10 between which is inserted suitable cushioning 9 is completely finished off in a single operation, and its connection to the sole heel-shank monoblock is made with common shoemakers adhesives without the need for coverup or false pieces, above all offering openheel footwear an appearance (see FIG. 4) superior to that currently known inasmuch as the heel or butt of the sole 3 remains hidden in the upper offset of the heel l and the latters upper edge fits on the insole 10.

l claimi 1. In a shoe having an instep the combination comprising;

a. a heel, said heel having a top and a bottom, a front and a back and two sides and a periphery;

b. a shoulder extending upwardly from the top of said heel, said shoulder being at the periphery of the heel and being continuous and extending upwardly from the two sides and from the back of the heel;

c. a plurality of layers affixed to said heel said plural ity of layers including:

i. the sole of the shoe a part of which is adjacent the top of the heel;

ii. a layer of cardboard adjacent and on top of the sole;

iii. a metal plate adjacent and on top of said layer of cardboard;

d. said plurality of layers being affixed to said heel by at least two wood screws;

e. a shank piece adjacent to and on top of said metal plate, said shank piece:

i. extending to the instep of the shoe;

ii. having a longitudinal extent and having a central recess therein whereby the shank piece is reinforced;

iii. being affixed to the said heel by at least one wood screw;

the total height of the said plurality of layers in combination with the shank piece being less than the height of the said upwardly extending shoulder;

g. an insole on top of and immediately adjacent the shank piece.
